Bella Extreme is pleased to announce the release of the new 3205 MK III Power Amplifier. The 3205 MK III is a very rugged vacuum tube amplifier operating in Class AB providing 60 watts of glorious tube power using 6550 or KT88 output tubes.

The original BE 3205 and 3205 MK II amplifiers have become classics within the Bella Extreme lineup. When we discontinued these products, we caught nothing but grief. To keep our customers satisfied, we started improving the 3205 design and then the development of the 3205 MK III power amplifier

The power supply uses a large mains transformer designed exclusively for the 3205. All circuitry is point to point wired and maintains the same high level of craftsmanship and quality that has always been known throughout Bella Extreme products. At Bella Extreme, we do believe in using only quality passive components in the manufacturing of our products. One look under the hood and you will see some of the most highly regarded audio component parts assuring the 3205 MK III will become yet another classic.

The 3205 MK III was designed and voiced to be mated with our BellaMax preamplifier but can easily be driven by any quality tube, solid state or high quality passive preamplifier and/or home theater processor.

The 3205 MK III is housed in an enclosed high quality steel enclosure with a 1/2" solid hardwood front panel. See front panel wood options below.

Due to some supply problems with our chassis manufacturer, the 3205 MK III is currently on hold.
